We love a good crossover, and at this year's San Diego Comic-Con, there was a bunch of them, especially in the toy department.

There are three things right now in the entertainment world that appear to be guaranteed money-spinners: sequels, remakes, and crossovers. For the sake of this article, we'll be focusing on that last one. Elements and characters from one universe showing up in another. For fans of one or more of the franchises involved, it is always an incredibly exciting prospect.

Most of the time, examples include one superhero showing up on another's turf, or a game in which characters from different worlds can do battle, i.e. Super Smash Bros. At this year's San Diego Comic-Con, we got a slightly different spin on the crossover genr: X-Men Barbies, or perhaps it would be more accurate to call them X-Women in this instance.

Polygon reported that the collection has been created by Mattel to celebrate Marvel's 80th anniversary. And the release of X-Men: Dark Phoenix earlier this summer, of course. Three X-Men have been turned into Barbie dolls: Mystique, Storm, and Dark Phoenix. The three of them will be GameStop exclusives and go on sale later this year on October 4. Individually they'll cost $54.99, or you can buy all three as a bundle for $164.99.

GameStop will be getting another exclusive crossover collectible selection of figures later this year too. A collection that celebrates the successful Batman vs Teenage Mutant Ninja Turtles animated movie. All packs will include one character from each universe, ensuring that fans have someone from Gotham and someone from the sewers. The packs will be released gradually with the first two coming on September 2, 2019.

The first two packs released will include Batman and Leonardo, as well as Robin and Raphael. Each pack will cost $49.99 or, once all five packs have been released, you can buy all 10 figures for $249.99. Other packs will feature Batgirl, Shredder, and Ra's Al Ghul. This is plenty of good news for fans, kids, and collectors to get excited about above, and not too long to wait until the packs are released in your local GameStop.
